When precision cnc processing plants produce products, small mistakes of operators often lead to product deformation, which affects the production efficiency of enterprises. So how to reduce cnc machining deformation of mechanical parts? Let's take a look.
Heat treatment processing: for precision cnc processing of parts, due to a variety of reasons, products are prone to bending after heat treatment. On the one hand, there will be bulges in the middle and the plane deviation will increase, which is caused by improper operation of the operator, but this rarely happens in our company; On the other hand, due to various external factors, the fixture has bending phenomenon. These deformation problems are not only due to the change of internal stress after heat treatment, but also due to the weak professional knowledge of operators and the lack of understanding of the structural stability of products, which increases the probability of part deformation. It is also important to read the drawings accurately and carefully and process machine parts according to the drawings.
Clamping too tight: auxiliary tools are often used to clamp products during precision CNC machining. In order to avoid vibration during cnc processing of products, this method is used, but there will also be some similar situations of heat treatment. At this time, adjust the clamping force according to the position of the clamping point to increase the contact area between the fixture and the workpiece as much as possible. This treatment will be much better, thus reducing the deformation of precision cnc machining.
Tool cutting: due to the insufficient rigidity of the product or tool and the influence of the cutting force, the product is thicker and thinner, which is called tool feeding. The way to deal with this phenomenon is to improve the sharpness of the blade and reduce the friction resistance between the blade and the workpiece.
